It operated for about one month. References: Don P. Mitchell: Sputnik 3. Cite this page: Copy to clipboard. It was detached from the carrier rocket, which is travelling along a similar orbit. Moscow time on May 15 it passed over Moscow from the south-west to the north-east. Soviet Sputnik 3 is in the form of a cone 1. It weighs 1, kilogrammes. The weight of the instruments for scientific research, the radio measuring apparatus and the sources of electric power aboard weigh kilogrammes.
Instruments are installed in the sputnik to study the pressure and composition of the atmosphere in its upper layers; the concentration of positive ions; the magnitudes of the electric charge of the sputnik and the tension of the Earth's electrostatic field; the tension of the Earth's magnetic field; the intensity of the Sun's corpuscular radiation; the composition and variation of primary cosmic radiation, the distribution of the photons and heavy nuclei in cosmic rays; micrometeors; the temperature in the sputnik and on its surface.
The programme planned for the sputnik will make it possible to study a number of geophysical and physical problems with the aid of the instruments taken up by the sputnik to great heights. A multi-channel telemetering system with a high selectivity has been installed on the sputnik to transmit the data to recording stations on the Earth. The sputnik is equipped with special transmitting devices which enable the co-ordinates of its trajectory to be measured.
With the aim of enlisting broad scientific circles in the observation of Soviet Sputnik III, a radio-transmitter has been installed in it which constantly emits powerful telegraph-beats on a frequency of A programme device controls the operation of the scientific and radiotechnical instruments aboard the sputnik.
Apart from electro-chemical batteries the sputnik is equipped with solar batteries. A thermal regulating system which, with the aid of special devices, changes the coefficients of radiation and reflection of the sputnik's surface serves to ensure a temperature regime for the normal operation of the apparatus on board. Observations of the sputnik, registration of the scientific data and the measurement of the co-ordinates of its trajectory are being carried out by specially organised stations equipped with great quantities of radiotechnical and optical instruments.
Sputnik had a diameter of 22 inches and weighed pounds and circled Earth once every hour and 36 minutes. Traveling at 18, miles an hour, its elliptical orbit had an apogee farthest point from Earth of miles and a perigee nearest point of miles. Visible with binoculars before sunrise or after sunset, Sputnik transmitted radio signals back to Earth strong enough to be picked up by amateur radio operators. Those in the United States with access to such equipment tuned in and listened in awe as the beeping Soviet spacecraft passed over America several times a day.
Students Doing Tons of Homework. Officially, Sputnik was launched to correspond with the International Geophysical Year, a solar period that the International Council of Scientific Unions declared would be ideal for the launching of artificial satellites to study Earth and the solar system. Sputnik was some 10 times the size of the first planned U. The U. The first U. By then, the Soviets had already achieved another ideological victory when they launched a dog into orbit aboard Sputnik 2.
The Soviet space program went on to achieve a series of other space firsts in the late s and early s: first man in space, first woman, first three men, first space walk, first spacecraft to impact the moon, first to orbit the moon, first to impact Venus, and first craft to soft-land on the moon.
